Wales coach Warren Gatland says none of his France-based players have become better players by crossing the Channel.

Centre Davies will win his 50th cap when he lines up alongside Harlequins' Jamie Roberts, formerly of Racing 92, against Scotland on Saturday.

"I don't believe that any of our players have improved going to France," said Gatland.

Davies admits he has not always been at his best since being in France, adding: "But it's all about learning."

He returns to Scarlets at the end of the current campaign and added: "I've learned off some of the best players in France, and the experience of playing at such a passionate club has been good.

"You cannot emphasise how important rugby is to them, and how the emotions are in French rugby.

"The last few weeks, our results haven't gone to plan, but I have enjoyed it and I think I've learnt about myself.

"Living out there on my own, you have time to think about stuff. I'm not very philosophical as such, but at the time it was the right decision for me to go out to Clermont.

"And now, making the decision to come home is the right one now."

Gatland says it is "great" Davies is returning to the Scarlets after two years at Clermont Auvergne.

"So the fact Jonathan has decided to come back home and we can have more hands-on with him and work with him... hopefully we will see him getting back to where he was and improving his game," added Gatland.

Gatland is looking forward to seeing Davies continue his "pretty special" midfield partnership with Roberts when Wales play their first home game of the Six Nations.
